esp32 in slave mode, using UART and SPI

Postby nitzanr » Mon Nov 20, 2017 12:14 pm

Hello

I try to understand the interface connectivity of the chip.
My plan is to connect Uart for control and Spi for data interface.
If I use VSPI, the VSPIQ pin is using VIO supply, which is 3p3V while the rest of the VSPI pins uses VSDIO which I would like it to be 1p8V.
will it work that way?
any other solution/idea for connecting UART and SPI both on 1p8V ?

Thanks
